"Painting is for lazy people," Ajarb Bernard Ategwa's father would tell him as a child. Daydreaming and doodling in his school books would often get him scolded as a boy. But the Cameroonian artist, now 30, tells the BBC he got the last laugh.

Ategwa says his vivid paintings of life in Cameroon's biggest city, Douala, sell for up to £20,000 ($26,000).

He jokes that family members educated to a higher level than him "now respect me a lot... because I am the most successful".
